Spread Mooring systems
Spread mooring systems are multi-point mooring systems that moor vessels to the seabed using multiple mooring lines.
While the vessel is in a fixed heading relative to the seabed, its bow typically heads into the dominant environment which is usually the direction where the largest waves are coming from.
The mooring lines can be directly attached to the hull of the vessel as well as indirectly using buoys on the sea surface. When they are directly attached to the hull, structural modifications are required to provide strong points for the mooring lines. Spread mooring systems with buoys are called Conventional Buoy Mooring (CBM) systems and do not require any modifications to the vessel hull structures.
